redis中hget方法传参规范问题

改node.js中socket遇到的问题

var socket.uid = 1;
clientRedis.hget( "LiveConnect_pull",socket.uid);
报错：This is converted to "[object Object]" by using .toString() now and will return an error from v.3.0 on.

改成以下就好了：

clientRedis.hget( "LiveConnect_pull",''+socket.uid+'');

原因很明显啦，传参要求格式必须是string
